◆ Making Soft Ice Cream

1. Install the air tube properly; insert the end with a side hole into the exit pipe. 2. Pour mixes into the hoppers and the mixes will flow into the cylinder from the hole in the bottom of the air tube.

3. Pay attention to the discharge port, when the liquid mix can flow out of the dispenser, it’s time to push the “start” button.

4. When the process starts, the beater motor runs immediately,followed by the compressor after a while. 5.When the mix achieves the certain hardness, compressor will stop automatically. About 40 seconds later, the stir motor will stop itself. Press down the dispenser handle, and you will get the satisfactory soft ice cream.

6. After the machine remains idle for two to five minutes, beater motor and compressor run again and refriger- ation process resumes. When temperature of the mixes in the cylinder rises above a threshold value, refrigeration process resumes until certain hardness is reached.

7. When an ice cream making process ends, the user can stop refrigeration and clean and disinfect the machine according to the manual. Power off the machine at last.

Precautions and

Maintenance

Section 1 Precautions for Use and Preventive Measures ◆ Environment 1. The operation of the machine should be in a relatively dry environment, and the air humidity should not exceed 90% generally, the altitude should not over 2000 meters.

2. Normal ambient temperature should range between 10℃ and 38℃. Avoid extreme high temperature. 3.Avoid usage in the sunlight or in the rain. Do not let water or mixes infiltrated into machine. 4. Avoid working in the serious dust containing area or corrosive gases environment. 5. Maintain good ventilation around the machine and avoid usage in the locations where the space is narrow. 6.Watch out the rats and pests near the machine.

◆ Key Point of Safety 1.Keep good ventilation This machine is air-cooled model, the machine is air-cooled models, in the cooling state, and the machine has a strong hot air discharge to ensure the normal refrigeration cycle. The operator should recognize that the ventilation area is not covered or jammed while using the machine. It is necessary to pay attention to maintaining good ventilation, which is very important to ensure the performance and lifetime of the machine.

2. Maintain the rated voltage In generally, the machine can be used in the normal range of voltage. If the power supply voltage is lower or higher than the allowable value, it will lead to automatic protection or damage to the machine. The operator should be aware of this situation and take appropriate preventive measures.

3. Protect circuit capacity The machine is high-power electricity equipment, the largest working current of which will be higher than 15A. If the supply line is too long or the diameter is too small, while start-up the machine, the voltage drop of the circuit will increase significantly, and resulting the actual supply voltage of the machine to drop. The machine will start difficultly, get damaged or even burnt. The machine needs an independent source power supply line, the section of which should be larger than 4mm²and the length should be as short as possible.

4.Reliable grounding protection Each machine’s power plug is equipped with standard earthing end marked with the grounding mark. When the machine left the factory, the grounding terminal has reliable connection with the machine, and earthing through the power cord grounding protection device. Before operating the machine, make sure the earthing device of the power supply terminal is reliable, to ensure the machine shell is reliable grounding to release static electricity or prevent possible accidents caused by failure.

◆ Reasonable use 1. Use the spare parts correctly, such as cover the hopper, thus to keep it with quality, safety and hygiene. 2.Use a reasonable ratio of fresh mix, and keep the fluidity of the mix, so as to accelerate the flowing speed of the mix if it is necessary. Do not add water in while the machine is working.

Section 2 Common Problems The phenomenon listed here may be related to your use of the raw materials, the environment factors, the

supply power situation, and the method of operation. Please try to improve the operating environment or operation methods to avoid such incidents. ◆ Machine malfunctions, no display at all. 1). Make sure that the power works properly and is on; voltage is normal; power connectors are compliant and

works properly. Check whether extensions cord or receptacles are burnt or deformed. A 220V, single- phase power output should normally range from 198V to 220V.

2). If the power supply master switch of the machine is turned off. Please turn it on. 1.Lack of or no mix in the hopper cause a frozen beater. 2.Too much water left in the hopper or cylinder after washing, causing a frozen beater after making ice cream. If the machine be protected frequently. A 5KVA alternating current is needed to increase the stability. Any situation above will lead to the self-protection of the machine. The minutes later, the machine will be back to the standby mode or manual restoration by push the “stop” button. If the ice has not melted, it will be protected and locked after a new start. When the voltage is back to 198V-236V，the voltage canceled itself.

◆ Machine can boot and cleans well, yet there is no quality ice cream discharged after a period of working. In this situation, the main control board works as usual. There is something wrong with the stir motor. Change the start capacitance, working capacitance, or motor to remedy the trouble. The essential reason is motor working under a low voltage for a long time. The suggestion is the machine needs an independent source power supply line, the section of which should be larger than 2.5mm and the length should be shorter than 6 meters.

◆ Machine cannot stop automatically. 1). Refrigerate too long time during the working, and cannot stop automatically. Push the“stop” button can

stop it. That is because there is no or too less mix flow into the cylinder, thus cannot achieve the demand resistance to stop the machine. Check the feed tube hole, to make sure mix can flow in to cylinder quickly. If it is almost the end of wor-king, stop the machine. Ambient temperature is too high. Check whether the Ambient temperature is higher than 38℃ or not and try to cool it down. Or if the condenser unwashed during a long time, use water with some pressure to clean the cooling fin of the condenser.

2).The “stop” button is invalid. Discharge door body in a working location or spring inserted link gets stuck. Remove the spring plunger back to the original position.

◆ The ice cream is too hard or too soft This situation is related to the following factors:

1)The hardness gear setting is not appropriate: need to set hardness level to higher or lower 2)Problem of raw material: Please contact the supplier and change the mix. 3) Don’t make the ice-cream before the cooling being finished. You may do it until the machine stops autom- atically.

4) The machine is cooling too long time with less mix, so the ice-cream will be too hard. ◆ The machine is making big friction noise while operating, and cannot discharge ice cream or mix. The

machine got frozen-up. Definition: The frozen cylinder phenomenon probably occurs when there is ice in the cooling cylinder because the mix has high freezing point or the machine is in cooling too long. This will result in the rise of stirring torque, which will lead to the damage of the worm gear and worm reducer, even can be burnt down the motor of the machine. Please operate carefully to avoid frozen cylinder phenomenon. Reasons and avoidance measures: 1. The mixing rate between the soft ice cream powder and the amount of water must follow the manual. It tends to be frozen if the mix contains too much water. 2. Remember to remove all the water from the cooling cylinder after cleaning or frozen cylinder phenomenon would happen 3. The machine has been refrigerating for a long time without mix, which will lead to frozen cylinder phenomenon.

So please make sure that there is enough mix in the hoppers while the machine is working.

Warning: All the maintenance, repair work must be carried out when the power supply is disconnected. Please confirm the power has been cut off before opening panels of the machine.

Stop the machine for 20min, press the ”Stop” button, restart the machine when the temperature of the cylin- der rises and the ice melts naturally. Then discharge the water completely in the cylinder, put the air tube at its original place, start producing the ice cream finally. ◆ The mix drip out from the discharge door There is some room left near the discharge door to ensure the wellness of the shape of ice cream.The remains of the ice cream at this place will melt and drip. Please use the drip tray appropriately, and clean the drip in time. ◆ The leak of the discharge door The hand screw of the discharge door goes loose. Please tight it up with force, and keep the edge of discharge door and the commissure of board parallel. ◆ The leak or the mixture of different mix of draw valve The O-ring draw valve is not installed or has been seriously damaged. Please pay attention to the draw valve in the middle place which differs from the two other ones in structure. Use the proper O-ring and install it well.

Table of soft ice cream machine power line’s parameter The national standard and ICE stipulate that the voltage of electric equipments

should range from 185V-250V, so in order to meet the requirement, please guarantee your power line capacity, and dispose your line according to this table while the machine is operating.

(City center--Distribution center--Distribution box--Outlet--Ice cream machine)

Explanation 1.The cable must have 3 cores at least: L phase line + N null line + PE protective grounding. 2.While counting the charge of the ice cream machine, 20A or a higher meter is necessary. 3.If the local power grid is unstable, install a 5KVA power stabilizer on the socket before the ice cream machine.

Configuration of Power Line

Appendix 1 The normal voltage of the soft ice cream machine ranges from 198V to 242V In order to meet this condition.

When the power is higher than 3.5KW, we have to equip a standard power line. There are too many factors will affect to the voltage: the supply condition of a city’s electricity, accident and so on. The main factor you can control is to reduce the loss of the power line. Please read the table below, and equip a suitable line for your machine to reduce the loss of power line. In the table below, the power supply line is divided into two segments (level). In general, supplying the

electricity from distribution center to electrical terminals directly is not allowed because it is unsafe. If power the supply line has two or more segments, you can refer to the first paragraph. This table is designed for soft ice cream machine only, if you have to add other electric equipment within this

power supply line, please refer to the table and figure out your power. Take a 1000~1200W electric equipment for example, figure out the conversion coefficient K first. K=the total power of all electrical appliances / the rated input power=1200W/2400W=0.5.Then, figure out the corresponding reference data in the table. If you have to calculate the data in segment 2, row 3, and the line is 50 meters long, the sectional area of the cable is:6/K=6/0.5=12 (mm²), so you should choose 16mm² cables. When the cable’s cross-sectional area is 6mm²

unchangeably, the length of the cable should be 50*k=50*0.5=25(m). Dear customer, if you find the operating voltage is not range from 185V-250V or 350V-410V, please ask a

certified engineer to check it. Please make sure that your power supply line is in accord with the requirement in this table if other factors are normal.Table of soft ice cream machine power line’s parameter.The national standard and ICE stipulate that the voltage of electric equipments should range from 185V-250V, so in order to meet the requirement, please guarantee your power line capacity, and dispose your line according to this table while the machine is operating.

Motor power transfers to the magnetic stirring component through the pulley and belt. The blades (magnet inside) in hoppers are drove by the magnetic stirring components (covered with magnet) which are under the hoppers. The rotation of the blade makes the mix in the cylindersflows. Motor holder is installed on the left side’s beam of machine; magnetic components are installed in the bottom of the hoppers, sealed with O- ring. 2. Features The magnetic stirring keeps the mix at a proper temperature and achieves best fresh-preserved result by the stirring of the blades in coppers. A lower mix temperature speeds up the production of ice-cream in the cylinders and prevents the mix layering. 3. Disposals of malfunction Magnetic stirring blade does not work 1. Please check whether the temperature of mix in hoppers is too low or not. The material’s temperature’s being too low would result in the bad fluidity of the mix and cause the blade not able to rotate normally. 2. Please open the panel which is near the magnetic system motor. Check if the belt got loosen.Loosen the tension pulley nuts and tighten them after adjusting the belt pressure, if necessary. 3. Please open the cover of magnet (No.10), check the screw of the magnet (No.9), and make it tight if it is loose.

The Instruction of Air Tube

◆ Air Tube Introduction · The Air tube is a kind of structural parts that increases ice cream puffing rate. The inner of the cylinder will

form partial vacuum after the ice cream made. The mixtures and the air will be socked into the cylinder at the same time. Stirring equally through the beaters so as to achieve the puffing effect.

· The structure of air tube shows as the picture1: there totally has seven sealed o-rings in up and down and two air tubes. The hollow inside of the air tube is the air inflow channel, the air will has two times path changing. when it flows. Always keep the feeding entrance close to the bottom of the hopper when you use the air tube.

· The ice cream puffing rate can be reached 20% to 30% after you used the new-developed air tube.

◆ Air Tube Usage · Clean the air tube before using. Smear a little bit of food lubricant on

the button of the O-sealed,insert it in the feeding entrance of the cylinder, then pour the mixture into the hopper. Press the “Clean” button, shut down the “Clean” button after 3 to 5 minutes, then press “Auto” button.

◆ Air Tube Cleaning · Pull out the air tube when you wash the machine, then insert it into the feeding entrance after inverted the direction of the air tube. Pour some water to wash the hopper. Pull out the air tube again after the hopper washed, Wash the air tube with sanitizer mixed water.It’s not recommended to use superheated water to prevent deformation and aging of the air tube gaskets.

◆ Attention 1. Recommendation: Use the feeding entrance corresponding to "1" or "2" when the mixture is viscous; Use the feeding entrance co- rresponding to "3" when the mixture is dilute.

Steps ： 1、Put all parts of air-pump in water, and wash them with brush. 2、Dip all parts of air-pump in the disinfectant for 10 min and wash it with brush.(see the following chart). 3、Wash all parts of air-pump with pure water for 3 times. 4、Wipe the water and put them away.

·Brush operation instruction please use the following brushes to clean parts of an air-pump. Brush 1 is used to take out sealed O-rings.

Please use the right brush to clean different parts of an air-pump according to the number.

◆ Steps of using the pump 1.Assemble the pump properly 2. Pour the ice cream mix into the hoppers 3. Connect the machine to power and press the “Clean”button. After the air-pump been working for 10 minutes, press the “Auto”or “Manual” button to set the machine into ice cream making process. 4. Shut the cover of the hoppers and wait until the ice cream making process ends. 5、When the machine is in automatic mode, if no ice cream has been sold for over half an hour, please extrude 150ml ice cream through the left and right nozzles separately (300ml in total). And put it in two hoppers with proper stirring, in order to promote slurry recycling and to prevent freezing and to reduce the emergence of bubble. 6、While ice cream hasn’t been sold out for a long time (over 1 hour), please change the system into automatic mode and adjust the hardness value to 0 or 1 degree. - It’s a normal phenomenon that some ice cream slurry overflowed from the two small holes on the pump while the air-pump is running normally.The overflow slurry, dropping to the hoppers can be used continuously. 7、little ice cream mix may come out from two holes on the air-pump cover. This is a normal phenomenon. The ice cream mix will come down to the hoppers, making circulation itself. 8、Remember to frequently observe the amount of material in the tank and add if the ice cream mix level is too low.

Note:The sanitizer is offensive to skin and in jured parts. Please protect your eyes, nose, mouth in jured skins from the disinfectant when cleaning. And wash it with pure water if it happens or go to the doctor’s.Please make strict use of sanitizer and keep it away from children.
